WHEN it comes to a person’s first kiss, most people should be thankful it probably happened in private, away from prying eyes and video cameras.

But when it comes to Logie winner Samuel Johnson, the actor wasn’t given that same luxury, today revealing his first kiss was on Channel 7’s hit soap Home and Away.

Johnson had a brief stint on the show back in 1995 starring as Kate Richie’s badly behaved boyfriend Gus Bishop and it was his fake relationship with the Aussie star that led to them having to kiss on camera.

Taking to Facebook, the Aussie actor, who won this year’s Gold Logie for his portrayal of Molly Meldrum in Molly, explained the hilarious story.

“Kate Richie was my first kiss. Not my first screen kiss. My first real, actual kiss. And it was on-screen!” he wrote.

The actor has become an advocate for the charity Love Your Sister, which was set up to raise money for his sister Connie Johnson after she was diagnosed with cancer.

Johnson told the embarrassing story to thank Ritchie for her donation to the charity.

“Many years later I hid from her when we were shooting Underbelly II, because I was still so embarrassed. And now, without me having any clue, she’s gone and put her heart print in with Connie’s and mine, in support of ‘A Heart as Big as Yours’ — villager Maria Ramos’s $100,000 art fundraising project,” he added.

Despite Johnson’s very first kiss forever being a part of the Home and Away archive, the actor revealed why he’s thankful to Ritchie.

“What started as a very awkward kiss 20 years ago has blossomed into a beautiful heart, made of her finger prints, in support of cancer research. What a champ. Thanks for putting a beautiful ending on my awkward tale of woe Kate!” he ended.

Richie also took to Instagram to post a photo of herself with the artist Maria Ramos, encouraging others to join the cause.

Johnson’s sister Connie is the final stages of breast cancer after she was diagnosed with cancer at the age of 11.

The actor has been instrumental in cancer fundraising efforts for over a decade first raising money for the children’s cancer charity Canteen back in 2003 when he rode a unicycle from Sydney to Melbourne.

Johnson went on to break a Guinness World Record in 2015 after he rode 15,955km around Australia and raised $1.47 million for the Garvan Institute of Medical Research.

The siblings’ biggest fundraising effort came in April this year after the Logies Awards.

The duo encouraged their followers to throw 5c pieces into a huge heart in Canberra. At the end of the fundraising effort, they’d made $2.535 million.
